TIRE.

Specification of Letters Patent.

latented July 3, 1906.

Application filed October 16, 1905. Serial No. 282,962.

- To all whom, it may concern.-

citizen of the United States, residing at Chi .cago, in the county of Cook and State of Illiand useful no s, have invented certain new Improvements in Tires and I do declare the following to be a full, clear, and exact description of the invention, such as will enab e others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in elastic tires for-the wheels of automobiles and other vehicles.

The object of the invention is to provide a simple, inexpensive, and eflicient means for elastically mounting tires of any description upon the rims or fellies of wheels.

With the above-mentioned and other obj ects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be hereinafter more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a side elevation of a wheel constructed in accordance with my invention, parts being broken away to more clearly illustrate the construction. Fig. 2 is a transverse sectional view taken on the line 2 2 of Fig. 1, Fig. 3 is-a transverse section taken on the line 3 3 in Fig. 1, and Fig. 4 is a detail sectional view taken on the line 4 4 in Fig. 3.

Referring to the drawings bynumerals, 1 denotes the wheel of an automobile or other vehicle, which consists of a'hub 2, spokes 3 radiating therefrom, a felly 4, and a tire 5. The tire 5 may be of rubber, metal, or any other material and of any desired form and construction. -The felly 4 has in its periphery a deep annular groove 6, and it is preferably formed in two sections, a main portion 7 and a removable ring which is secured upon similar fastening means is here shown in the form of a ring of solid one side byscrews or "the bottom of the or annular plate 8, j may 9. The tire 5, which i rubber of circular form in cross-section, is disj porte by a series of studs or pins 11, which i and the minor details groove 6, which latter is formed from said block or plate.

project inwardly through slots 12, formed in the folly, and have upon their inner ends coilsprings 13. The latter are confined between t e folly and which are provi ed upon the screw-threaded ends of the pins or studs 11, as clearly shown in Fig. 3 of the drawings. springs and the ends of the pins may be inclosed in casings 15, secured u on the felly, as shown. The studs 11 are he d centered in the slots 12 by means of pairs of coil-springs 16, which are disposed inre'cesses 17, formed in the felly upon opposite sides of said pins or studs. These coil-springs 16 surroundpins 18, which slide in reduced portions of the recesses 17 and which have upon their adjacent ends grooved heads 18,- Which engage the pins or studs 11 at diametrically opposite points, the

sprin s being confined between said heads and s oulders formed in the recesses 17, as clearly shown in the. drawings. This construction permits the rim 10 to slide transversely and also swing longitudinally to a slight extent. The rim 10 is elastically supported by a series of segment-shaped blocks or plates 19, which have a curvature similar to the curvature of said groove. These blocks or plates are disposed between groove 6 and the inner face of the rim 10 and are elastically supported by one or more coil-springs 20. As shown in the drawings, but one of the springs 20 is provided for each block or plate, and. it surrounds a pin or stud 21, which projects inwardly Said coil-springs 20 project through apertures 22, formed in the felly, and into casin s 23, which are socured upon the folly, as s own. In said casmgs are provided set-screws'24, which have .airs of adjusting-nuts 14,

If desired, the

springs '20, so that the tension of the latter be readily adjusted. Suitable jam-nuts may be provided upon said screws, as shown. Instead of employing a rubber tire, as shown in the drawings,-I may make the rim or tire 10 sufficiently thick to cause its outer surface or periphery to project beyond the outer edges of the groove 6.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood Without requirmg a more extended explanation.

Various changes in the form, proportion,

of tonstruction may be resorted to withoutdeparting from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a wheel, the combination with a felly having in its periphery an annular groove, of a tire in the outer portion of said groove, a loosely-mounted rim within said groove for supporting said tire, a series of segmental plates or blocks within said groove and beneath said rim, springs for elastically supporting said segmental blocks, radially-disposed studs projecting; inwardly from the inner face of said rim and through openings in said telly, coil-springs upon thefree ends of said studs, and adjusting devices upon said studs.

2. In a wheel, the combination with a felly having in its periphery an annular groove,

of a tire in the outer portion of said groove, a loosely-mounted rim within said groove for supporting said tire, a series of segmental plates or blocks within said groove and be neath said rim, springs for elastically supporting said segmental blocks, varying the tension of said springs, radiallydisposed studs projecting inwardly from the inner face of said rim and through slots in said telly, nuts upon the threaded ends of said studs, coil-springs upon said studs between said nuts and said felly, and means for centering said studs in said slots and holding them in a radial position.

3. In a Wheel, the combination with a felly having in its periphery an annular groove, of a tire in the outer portion of said groove, a

means forvarying the tension of said springs, radiallydisposed studs projecting inwardly from the inner face of said rim and through slots in said telly, nuts upon the threaded ends of said studs, coil-springs upon said studs between said nuts and said'felly, pins Islidable in recesses in said felly and disposed upon opposite sides of said studs, heads upon sai pins andengaged with said studs, and coilsprings surrounding said pins and confined between their heads and shoulders in said recesses, substantially as described.

4. In a wheel, the combination with a telly having in its eriphe'ry an annular groove and a series oi radially-disposed slots. of a tire in the outer portion of said groove, a rim in said groove for supporting said tire, a series of studs projecting inwardly from the inner 'face of said rim and through the slots in said telly, adjusting-nuts upon the threaded ends of said studs, coil-springs upon said studs between said nuts and said telly, and coil-springs adjusted upon op osite sides of said studs for centering the atter in their slots and maintaining them in radial position, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses. v WILLIAM A; FIELD.
